Use their knowledge of number sequence to order numbers.
Activity
The students play this game in pairs. One partner chooses a number between 0 and 1000 and writes it on a piece of paper without showing the other person.
The person guessing asks questions about the size of the secret number. For example "is it smaller than 500?".
The person with the secret number answers "yes" or "no".
The students can count the number of question it takes to guess the secret number.
